The object of processing is to extract the solid rubber from the latex liquid in the same way that butter is made from milk. Originally latex was diluted with water and poured into coagulation tanks, Acetic or Formic acid was added and after stirring and straining produced 30-35% rubber content. The "curd" was then squeezed between rollers to produce latex sheets. This method has now been largely replaced by massive centrifuges.
